Abstract:
OBJECTIVETo study the chemical constituents in the buds of Tussilago farfara.
METHODThe chemical constituents were isolated by various column chromatographic methods and structurally elucidated by NMR and MS evidences.
RESULTEleven compounds were obtained and identified as methyl 3, 4-O-dicaffeoylquinate (1), methyl 3, 5-O-dicaffeoylquinate (2), methyl 4, 5-O-dicaffeoylquinate (3), 3, 5-O-dicaffeoylquinic acid (4), methyl 3-O-caffeoylquinate (5), 3-O-caffeoylquinic acid (6), hyperoside (7), rutin (8), kaempferol 3-O-beta-D-glucopyranoside (9), quercetin (10), and kaempferol (11).
CONCLUSIONCompounds 2-5 were isolated from the genus for the first time.
